NWS Forecaster Discussion

Area forecast discussion
National Weather Service Austin/San Antonio Texas
322 PM CST Tuesday Mar 3 2015
Short term (tonight through Thursday morning)...fog will be the
issue again tonight. Areas along the I-35 corridor are still
seeing some visibilities below a mile. Fog will expand in coverage
across the area this evening and overnight...becoming dense where
it already is not. A dense fog advisory will likely be needed for
a portion of the area. Patchy drizzle and isolated showers
possible along and east of I-35 overnight and through midday
Wednesday. Elevated showers may clip far northwest areas of the
County Warning Area during this time with approach of middle level shortwave and
moist axis.
Much advertised cold front still on track to enter northern areas
of The Hill Country and central Texas Wednesday afternoon. Cold
dense airmass behind this front...with front accelerating quickly
through the remainder of the County Warning Area early Wednesday evening. Very
sharp temperature drop behind the front...and strong pressure
rises will result in windy conditions areawide. Winds potentially
approach Wind Advisory criteria along the edge of the Escarpment
and eastward through the coastal plains.
The forecast philosophy has not changed much with respect to precipitation
chances behind the front and potential for winter precipitation across
the northern half of the County Warning Area. Deep forcing continues behind the
front peaking west to east between 06z-12z as middle level shortwave
passes by. Favorable upper level jet positioning will assist in
ascent across the northeast half of the County Warning Area. Top down look at
forecast sounding as well as sref plume from NCEP indicate
predominate precipitation type will be freezing rain mixing to sleet.
There will be a very slight chance and small window for light
snow to mix in across the far northern Hill Country Thursday
morning.
Areas along and north of a Comstock to Concan to Helotes to San
Marcos to Lexington line are currently where we are expected the
potetnital for ice accumulations...ranging from a trace to 1/10
of an inch. This includes the Austin metropolitan area. Can not rule out
some sleet south of this line...but ground temperatures should be
above freezing. Can not rule out a few spots along a kerrvile to
Johnson City to Georgetown line seeing accumulations just over
1/10 of an inch.
A Winter Weather Advisory will likely be issued in the next
forecast package...and depending on quantitative precipitation forecast trends a Winter Storm
Watch/warning may be required for The Hill Country and portions of
central Texas.

Long term (thursday afternoon through tuesday)...models have
trended faster with precipitation exiting the area Thursday morning...and
we no longer carry mention of weather Thursday afternoon. A more
widespread freeze is likely Friday morning as clouds decrease due
to continued drying and a cold surface ridge over our area. The
middle level shortwave reforms into a low across northern Baja California then
opens and moves across southern Texas this weekend. There are
differences between GFS and European model (ecmwf) with amplitude and speed of this
system. Have low chances for rain in the forecast Saturday night
through Sunday night. More seasonable temperatures finally return
to the forecast early next week...depending on speed of
aforementioned system
